Understanding how light and how different types of materials react with light, was a big part of our discussions for the initial part of the project.  Ann and I both felt that the children should understand how light passes through different types of materials early on in the project in order for a deeper understanding to develop.  Lots of investigations were carried out on a variety of materials.

Eventually we discovered that some of our materials blocked out the light, some let a little light through and some let lots of light through.  We used the investigations to help sort the materials and use them to create light wheels.  The children tried to layer up the different materials to create patterns for their wheels.  The results were amazing!!
